SLIDING AND SWINGING WINDOW Application filed October 1, 1929. Serial No. 396,583.

The present invention relates to improvements in double hung sashwindows and particularly to'that class of windows in which the lower sash is adapted to slide vertically in the window frame and also to be swung inwardly within the room.

An object of this invention is to provide an improvedcombination vertically sliding and inwardly swinging lower sash wh ch may be placed in afixed angular position with relation to the-upper sash and thus guide the air stream upwardly and prevent the entry of direct drafts incident to the use of the ordinary vertically sliding double hung sash windows.

Another object of this invention is the provision of improved means whereby the lower sash may be connected to hinged guide strips, in order to permit the lower sash and guide strips to be swung ]O1I1tly inwardly about their lower front edges, thus ma1ntaining an unbroken contact between the sill and the lower sash and preventing any rain from entering the premises at the sill level when the lower sash is swung inwardly within'the room. 1

Another object ofv this invention is to subdivide the present vertical inner guide strips into two sections, an upper fixed section and a lower pivoted section, and to provide improved locking means for maintaining the upper and lower guide strip sections in fixed vertical alignment, and also for maintaining the lower sash and lower guide'strip sections in variable angular relations with the upper sash and thus provide larger or smaller openings vfor ventilation to suit the convenience of the occupants of the house.

With the above and other objects inview, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the spirit or sacrificing any of the advantages of the invention.

Reference will now be had to the drawings, wherein like numerals of reference designate corresponding parts throughout the I several views, in which:

Figure 1 is a vertical section through a window casement embodying the present invention, and shows the upper and lower sash in their respective normal closed positions.

Figure 2 is a vertical section through the window casement and shows the lower sash swung inwardly.

Figure 3 is a section of the casement and lower sash taken on line 2-2 in Figure 1.

Figure 4 is a sectional view of a portion of the fixture used for locking the guide strip sections.

Figure 5 is a sectional view of a portion of a stationary guide strip section, showing a pulley mounted in a recess therein.

Figure 6 is a fragmentary view of the easement, showing the guide strip sections locked for the vertically slidable position of the sash.

In the illustrated embodiment of the inventlon the several views show a transparent glass window pane designated by the number 10, and this pane is secured to the stiles 11 of the lower sash 12, and the upper i sash 13, by the usual means well known in the glazing art.

As best shown in Figure 3, the stiles 11 are slidable between guide strips 19, 19, and parting strips 15, 15, secured in pairs on the side walls 16, 16, of the window frame. In the usual practice, the side walls are connected at their upper ends to the head of window frame at their lower ends to the sill of the window frame. Normally, the sashes slide vertically and are counterbalanced by means of sash cords 17 17 at the lower ends of which sash weights are attached.

For the purposes of this invention, each guide strip 14 is out into two separate upper and lower sections 18, 19.' The cutting position of the guide strips is designated by the number 20.

The upper section 18 remains fixed to the sidewall 16 and the lower section 19 is rockably positioned on hinge means 21, fastened to the sill of the window frame or casement 23 and can swing from the normal .vertical position inwardly into the room about their lower front edges as best shown in Figure 2. The form of the cut may be circular and preferably drawn along a radius having the hinge pin as center and the lower guide strip section 19 is made longer than the upper section 18.

Each lower guide strip section 19 isprov'ided with an elongated aperture '24; A guide pin 25 is positioned within the aper ture 24 and is secured to the side wall 16.

Each aperture 24 is. of the same width as the diameter of the respective guide pin 25, but is about one quarter of an .inch longer. When a pair ofupp'er and'lower guide: strip sections are in vertical alignment, the lower wallot the aperture extends below the guide pin. WVhen the lower guide strip sections are swung inwardly to an inclined position the lower walls of the apertures rise, as best shown in Figure 2, and

come in contact with the guide pins and prevent any further movement of the guide strips. The inward swing of the lower guide strip sections is thus predetermined and limited by the guide pins 25.

As bestshown in Figure 1, the lower horizontal guide strip 22,- has its sash engaging face beveled so as to allow a clearance space for the lower sash to swing inwardly, about its lowerfront edge. This beveled edge 26 extends the full length of the guide strip 22, which remains fixed to the sill and prevents any rain from entering the premises.

The lower guide strip sections 19, ,19,

I carry pivoted hook members 27 which may be'rotated so as to engage eye :bOltS 28 on the-lower window sash 12, when the lower sash is at its normal lowposition. The members 27 and 28 thus form means for connecting the lower sash to the sections 19, 19. WVhen the members-27, 28, are in locked relation and the lower guide strip sections are swung inwardly about the hinges 21 to an-incline'd position, the lower sash is rocked or swung inwardly about its lower front edgesby the hookm'embers 27 27, and assumes the same inclined position as the lower guide strip sections.

To lock the movable and stationary guide strip sections infixed' vertical position or in fixed angular positions, there is provided a sliding bolt'member 29, bolt handle 30, strike plate 31, adjusting sc rew 32 and a piv oted sleeve member 33 having an aperture 34: in which the bolt 29 is adapted to slide. As

- best shown in Figure 4, the sleeve member 33 is held in position on the guide strip section 18,.byineans of a plate 35 to which it is riveted. The plate 35 is fastenedto the guide strip in'any suitable manner. The

there have been provided pulleys 37 which,

are suitably mounted at the lower ends of from sight by the upper guide strip sections- 18, which have recesses38 formed therein. to receive the-pulleys.

A pull handle 39 may upper rail of the lower sash and used-for wardly. Q

9 Operation of invention:

-When it is desired to swing the lower sash:

inwardly from a vertically slidableposition, the hookand eye members 27, :28 are locked together, the opposite bolt-handles 30 are grasped'with both hands and the bolts. 29 are pulled upwardly until disengaged from the strike plates 31. The bolt members 29 together with the lower guide strip sections 19- are then pulled inwardly. The lower sash 12 being temporarily yieldably connectedtothe lower guide strip-sections by means of the hooks 27 .is also swung inward ly and locked in any suitable inclined position by means of the'adjusting screws 32 at the will ot the operator; The; pull handle 39 may also be used to facilitate the locking of'the lower sash and lower guide strip To restore the lower sash to; its vertical position, the b0lt1members'29 ,arereleasedand the handles ,30 'are grasped and swung outwardly until the lower sash reaches. its

position the upper and lower guideustrip sections 18', :19 are locked in vertical alignbe attached. to the lit inent and the lower sash is then in a vertically slidable position.

When the upper and lower guide strip sections are locked in vertical alignment, direct ventilation may be had by sliding vertically the upper or lower sash or both, and indirect ventilation may be had by swinging the lower sash inwardly about its lower side, and locking the lower guide strip sections and lower sash in angular relation with the upper sash.

Primarily designed for double hung sash windows, this invention utilizes all the guide strips and all other parts presently used on double hung sash. The windows remain in appearance substantially the same as they were before the device is applied. The point of attachment of the cords remains near the top of the sash. It is to be noted that While the device is applicable for installation on new buildings, it may be applied to old buildings by utilizing the old guide strips present on the particular window frame to be equipped for this form of ventilation. The locking fixtures 36 are designed so that both hands are required to release the lower sash and the device is practically inoperable by children.

It is thus readily seen that theobjects of the invention are accomplished by means of a novel and practical window construction which may be applied to dwelling houses and other buildings using double hung sash windows.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent is:

1. In a window having a vertically sliding and inwardly swinging lower sash, the combination of rockable guide strips hinged to the sill about their lower front edges and a fixed horizontal guide strip having a sash engaging face projecting upwardly from the sill and being bevelled to allow the inward swing of the lower sash on its lower front edge while said front edge remains stationary in contact with the sill, and yielding means connecting said rockable strips and said sash to cause said sash to follow the movements of the said strips.

2. In a window having a vertically sliding and inwardly swinging lower sash, the combination of rockable guide strips hinged to the sill about their lower front edges and a fixed horizontal guide strip having a sash engaging face projecting upwardly from the sill and bevelled to allow the inward swing of the lower sash on its lower front edge while said front edge remains in its normal vertical sliding plane and stationary in contact with the sill, and yielding means connecting the lower sash to the said rockable guide strips for causing it to follow their movements and non-pivoting pins se cured to the sides of the window and engaging elongated apertures in the said rockable guide strips to limit their inward swing.

3. In a window having a vertically sliding and inwardly swinging lower sash, the combination of rockable guide strips hinged to the sill and a fixed horizontal guide strip having a sash engaging face projecting upwardly from the sill and bevelled, hook and eye members, connecting the lower sash to the said rockable guide strips for joint inward rotation, non-pivoting pins secured to the sides of the window and engaging elongated apertures in the said rockable guide strips to limit the inward swing of the said guide strips and lower sash to a predetermined maximum, and means for locking the said rockable guide strips and sash in any desired intermediate position.
